Summary

The posterolateral overhang of the femoral component was measured using 3-D templating software. Rounded and reduced shape of the posterolateral corner in the femoral component would be beneficial.

Introduction

In total knee arthroplasty, patients sometimes have pain in the posterolateral part of the knee. One possible cause is the impingement of the popliteus tendon against femoral components. In the literature, the incidence has been reported to be 1–4%. The purpose of this study was to compare of two prostheses on the amount of posterolateral overhang of the femoral component using Three-dimensional (3-D) templating software.
